“One of the surest signs that a kid is overscheduled is when what used to be fun isn’t fun anymore,” says Dr. Edward Hallowell, author of Crazybusy. “Activities are like ice cream—they’re great, but when you have too much, it makes you sick.” How can you tell if she’s just growing out of a unicorn phase as opposed to protesting an overscheduled life? “They start saying no to everything that used to be fun for them,” says Dr. Hallowell. If it’s just grumbling about one activity, let it go—but if nothing seems to appeal to them anymore, take notice.
